Massive clashes took place between the security forces and civilians in protest against the incident.
Dozens of people were injured in the Himalayan province as government forces fired tear gas and pellet guns to quell the protests.
Protests erupted once again in north Kashmir's Bandipora district as outrage in the region grew after a 3-year-old girl child was allegedly raped by a youth during the month of Ramzan early this week.
Baseer Ahmad Khan - the region's top administrator - also appealed for calm and said in a statement that the "enquiry of Sumbal incident is being conducted on a fast-track basis". Protest rallies were taken out by students in south Kashmir as well.
"The heinous crime of rape of a minor in Bandipora is under investigation". "We are treating the accused as a major and not as a juvenile", the official said.
Reports said members of Jammu & Kashmir Ittehadul Muslimeen headed by Maulana Masroor Abbas Ansari (son of Hurriyat leader Abbas Ansari) assembled at Pratap Park area at Residency Road in Lal Chowk and protested against the incident.More news: Pompeo skips Moscow, visits Brussels for Iran talks

"One of the injured protestors is critically wounded", Pani said.
The man, who comes from the Sumbal area north of the main city of Srinagar and is thought to be 20 years old, has already been arrested. "We have not entertained the certificate issued by school principal" said a senior police officer.
A police statement later Monday said that protests had spread to northern Baramulla district where 47 security personnel and seven protestors were injured in the clashes.
The incident has resulted in vociferous demands for Sharia Law from Kashmiri leaders even as a Special Investigation Team (SIT) of the Jammu and Kashmir Police is probing the crime following the arrest of the accused.
Other parties and separatist groups across the state have also demanded exemplary punishment for the alleged accused. Society often blames women for inviting unwanted attention but what was this child's fault?
Demanding speedy justice for the victim and sternest punishment for the accused, Mirwaiz Umar Farooq appealed the people to maintain law and introspect: "Fervent appeal to all people of Kashmir to maintain unity and vigil especially in view of mischievous forces waiting to create a sectarian divide out of this most reprehensible crime against a child which is indeed a crime against all humanity".
